GAS BURNER.

Original application led April 11, 1924, Serial No 705,919. Divided and this application iiled September 21, 1927.

This invention relates to a device for effecting admixture of air with an explosive or combustible gas, this application being a division of the original filed April ll, 1924, Serial No. 705,919. The invention has for its foremost object the provision of a burner suitable for the eiicient generation of steam for power purposes, but 1t is in no wise limited to this or any other particular use.

A still further object of the invention is the construction of a novel multi-jet burner having a variable inlet for at least one of the constituents of the combustible mixture.

AA still further object of this invention is the provision of a multi-jet burner of this type in which the burner is mounted' within and entirely surrounded by the respective carrying members thereof.

Other objects will appear as the description develops. I

In the accompanying drawin is illustrated a vertical section througi my improved heater.

The apparatus is shown inthe drawing as a burner consisting of cooperating fixed and movable members, the fixed member 27 being arranged within a combustion chamber 28. The member 27 is formed with a plurality of apertures 29, preferably flaring at their ends, which apertures align with a plurality of similar but smaller apertures 30 formed in the movable member 31. Said movable member is secured to a sliding conduit or pipe 32. This conduit and the combustion chamber 28 are so relatively placed that the fixed and movable members of the burner lie more or less closely adjacent one another, normally with a small space 35 intervening. Said s ace opens upon an annular channel 33 which surrounds or partially surrounds the combustion chamber 28 and the sliding conduit. The channel 33 constitutes the means for feeding gas to the space 35, said gas being supplied by the conduit 34 connected to the channel 33. The lower end of the conduit 32 is open to the atmosphere forming an air inlet in case an induced draft is used or to some form of compressor or blower (not shown), the air passing in straight columns through the aligned apertures 30 and 29 to the combustion chamber. Gas in suitable proportions is drawn from the annular channel 33 into the space 35 by the moving air columns. When it is desired to increase the proportion of gas in the mixture, this is Serial No. 221,034.

done by manipulating suitable means, such the conduit 32 and with it the movable member away from theadjacent end of the member 27, in thi's manner widening the space 35 between the fixed member 27 and movable member 31. While this burner is particularly adapted to supply combustible mixture to an adjacent combustion chamber, it may be as Well used in connection with air and gas mixers, such as carbureters Which are remote from the combustion chamber.

It is obvious that the specific details of construction and configuration of parts described herein may be modified in various. ways without sacrificing the advantages of the invention oir-departing from the scope thereof as defined in the appended claims.

I claim i i l. An apparatus of the character described, including superposed and spaced combustion chamber and air supplying members, one being adjustable relatively to the other, an annula-r gas Supplying member surrounding and communicating with the intervening space, and selective means for moving the adjustable member to vary the gas supplying area.

2. An apparatus of the character described, including superposed and spaced combustion chamber and air supplying members, one being adjustable relatively to the other, a gas supplying member surrounding and communicating with the intervening space, a perforated member mounted at and within one member adjacent said space, and means for moving the adjustable member to vary the gas supply to said space.

3. An apparatus of the character described, including superposed and spaced combustion chamber and air supplying members, one being adjustable relatively to the other, an annular gas supplying member surrounding and communicating with the intervening space, a pair of perforated members carried, respectively, by the combustion chamber and air supplying member, a-nd means for moving the adjustable member to vary the gas supply to said intervening space.

4. An apparatus of the cla-ss described, including a pair of longitudinally aligned tubes having their adjacent ends spaced apart, one of said tubes being movable to-` ward and away from the other to vary the liti space between the adjacent ends of said tubes, means for supplying gas at said space, and means operable at`will for longitudinally adjusting said movable tube.

5. An apparatus of the character described, including two superposed and separated tubes, one being movable relatively to thc other to regulate the area of the intervening space, means for supplying gas at said space, and-a perforated member of substantially the area of the tubes within one of said tubes adjacent said space. y

(l. An apparatus of the character described, including two superposed and separated tubes, one being movable relatively to the other to regulate the area of the intervening space, means for supplying gas at said space, a pair of perforated members, one of said members being mounted in the lower end of the upper tube and the other member mounted in the upper end of the lower tube, and means for relatively moving the tubes to vary the space between said members.

7. An apparatus of the character described, comprising superposed spaced combustion chamber and air supplying members, one being adjustable relatively to the other, a member arried by one of said members and surrounding the space between said members, said last-named member having a channel communicating with said space, a perforated member mounted within one of said first named members adjacent said space and means for moving the adjustable member to vary said space. i

8. An apparatus of the character described, including combustion chamber and air supplying members arranged in superposed spaced relation, one being adjustable relatively to the other, an annular gas-supplying member surrounding and communieating with the space between said members, a pair of perforated members carried, respectively, by the chamber and air supply ing member', means for moving the adjustable member to vary the gas supply between said perforatedmembers, and/ an ignition means mounted in the combustion chamber.

9. An apparatus of the character described, including two superposed and separated tubes, one being movable relatively to the other to regulate the area of the intervening space, means for supplying gas at said space, a pair of perforated members, one mounted in the lower end of the upper tube and the other mounted in the upper end of the lower tube, means for moving said tubes to vary the space between said perforated members, andan ignition means mounted in the upper tube.

10. An apparatus of the character described, including two superposed and separated tubes, an annular ring forming a gas-- supplying means carried by one tube, overlapping the other tube, and in communication with both tubes at the intervening space therebetween, and manually operated means for moving one tube relatively to the other to vary the gas-admitting space between the two tubes.

In testimony whereof I have hereunto set my hand.
